I was looking for any small ships visiting when, like you, I was surprised how many big ships were coming. So I started compiling the sizes. I wondered if they would have trouble filling them with the current high cost of airfares and delays with people being able to renew their passports. I let mine expire during Covid, having no idea when I could travel overseas again, and not thinking there would be a big delay getting it renewed.
One small ship sailed by via Cairns.
